r = –5

r = 5

r = 2.2

r = 1.2

2. 2x + 12 = 18 – x

x = 3

x = 10

x = 6

x = 2

3. 8x – 3 = 15x + 18

x = –3

x = 3

x = 2.1

x = .9

4. 6y – 6 = 4y + 16

y = 2.2

y = –2.2

y = 11

y = 5

5. 3(x – 4) = 5(x + 2)

x = 11

x = –11

x = 1

x = –1

**Steve**, Thursday, November 29, 2012 at 3:27pmthese are all basically the same. Here's #5. It should help you on the others:

3(x-4) = 5(x-2)

expand to remove parentheses:

3x-12 = 5x+10

collect the x stuff on one side:

-2x = 22

divide by the coefficient of x: -2

x = -11

finally, check your answer!

3(-11-4) = 5(-11+2)

3(-15) = 5(-9)

-45 = -45

if you get stuck on the others, come on back and show how far you got.
